RALPH RAGAN ATTORNEY Patented Sept. 16, 1952 UNITED STATES PATENT OFFICE SPINNING, T-WIS'IING, AND'LIKE APPARATUS 16 Claims. 1

This. invention :relates to spinning, twistinggand like apparatus, andmoreparticularly-to improved mechanism to replace :the spinning-rings, travelers, flyers, throwers and the like ,on present forms of spinning andtwistingmachines.

In-apresent'form of:spinning and twisting apparatus known and used in the art, roving or fibers are fed through drawing rolls, thence through a thread guide centeredover therevolving spindle, thence through a traveler slidably mounted on a spinning ring, and thence at right angles irom the traveler to-fthe spool or bobbin which revolves-with the spindle. The rotation of the spindle wraps the yarn around the-bobbin and theyam carries :the traveler forward around the ring, but the friction .of the traveler sliding onthe .ring causes it to-lag behind the speed of the spindleso that the ,travelertwists the-rov ing orfibers intoa thread. In starting up on, an empty bobbin, ends arebroken down due to the yarn pulling closer to dead center when the IQ- tation of the bobbin tries to :make the traveler move forward around the ring. The traveler causes greater or less tension on the yarn depending upon the weightof the traveler and itsarea ofcontact with the spinning ring, and itis therefore necessary to change weights and sizes of travelers .whenvdifierent counts of yarn are produced. The surface speed of the traveler is quite limited and the. life of a traveler is comparatively short. Oilor grease used to lubricate the rings and travelers soilsthe thread when an end breaks down and whips against theseandother portions of the machine.

It isan objectsoftmyinvention toprovide mechanism which willeliminateor the above noted difliculties.

Another object of .my invention is to provide mechanism which makes it possible ,torun spinning and twisting .frames and like appa atus at speeds faster than is now permissible.

Another object of my invention is vto provide apparatus which can be installed upon prior art spinning, throwing and twisting frames now-in use .by makingminor changes and adjustments therein.

Another :object of my invention is to provide apparatus upon whichboth twisting and cable twisting operations can. be performed simultaneously.

Another object of:my invention isto provide apparatus which, is inexpensive to manufacture, durablezin construction aandeflicient in operation.

Other and further objects and advantages of my invention will be apparent from the following description taken in connection with the accompanying drawing'in-which likecharacters of reference designate correspondingsparts throughoutthe several views-and wherein:

In the embodiment of my invention-chosenlfor, illustration, aspindle l0 carries :thepspool-gdriving lugs -H and a disc 12 mounted for rotation therewithand upon which the spool .Or bobbin (.3 rests. Surrounding the, bobbin .13 is a ppt .14 having an open upperend and a lowerend whith-v is closed except for a central bore provided-with bronzebushing 15 through which the spindle .lli extends. Theside walls of .the.p ot unreprevided on the inside thereof with diametrically opposed keys l5, l6, l6", "5", arranged for. engagementin keyways or slotsl'l, [1311",],1"; respectively. in the periphery of the disc .12-

A main bearing l8 isarranged withitsinner race 19 supporting the pct 14 and its-outerrace 2%] carried bya housing ,2 i The pot L4 is al gned with the spindle in, and then the bearinghousing zl is secured, as byclamps 22, 22, anotherwise fastened to the flanged bushing 22" which.v

is set-screwed in place of the conventional .ring on the conventionairing rail23.

A thread guide bearing "24 has its inner .race 25 seated on the outer side, wall-of th not [4 near the top thereoi, and the outer race 26, of this bearing carries the .ring shaped .supportrim 2"! which lies flush with the open upper-,endof pot l4, and also serves as alubricati nseaLin the sealed-for-4lif e type anti-.triction bearine. Mounted upon the supportrim 21 at diagonalLy opposite positions are .the thread guides :28, :23 through which the .yarn 29 passes .to .the bobbin l3. An even number of fdiagonallv disposed threadguides are used .todistribute the weight evenly tomaintainbalanceinthe pot l4. li-l e thread guides .28, 28 areforrned inthershane of elongated hooks which are set at anangle, shown in Figl, v ryin s m whatiromerrieh angle to theradiusof the pot, so that szthe di ameter of the package builds up entire-bobbin 13 the thread passes overdifierentmzsitiommn the guide and this prevents thread cuttingrwhich is so objectionable in a. travel er-..where athenthread runsin only on position.

,nlso mounted upon the supporhrim ll are-a. pair ofupstanding windvanes. 3,0,:31'1' which=are diametrically disposed and spaced 90 from threadguides-28, 28' so as:to;maintain2balanee 1n the pot [4. By means of thekey holeslots in their bases, as shown in Fig. 1, these vanes are quickly and easily interchangeable with vanes of difierentsizes.

In addition, a pair of flexible brake arms 3 l, 3 l are atta lied to the support rim 2! at diagonally opposite positions chosen to maintain balance in the pot H. The brake arms 3i, 3! are provided with brake shoes 32, 32, respectively, which are pressed against the wall of the pot [4 when the pot is at rest and are thrown outwardly against a stop 33, when the pot attain a predetermined speed of rotation. '5' 1 In operation, the yarn or thread 29 passes through a thread guide 28 to the spool 13 'when the machine is started; and, as soon as the spindlecomes up to approximately one-half full speed, the brake shoes 32, 32 disengage so that the windvanes30, 30' cause the support rim 2'! and associated parts mounted thereon to lag behind the speed of the spindle and take'up delivery of the thread without jerking. It will also be apparent that this arrangement will permit starting without breaking down any ends of the thread being twisted, because the thread guide does not put any stress on the thread until the brakes are rleased.' Also, in stopping, the brake shoes again engage the pot when approximately one-half speed has been reached and prevent ballooning of the thread by causing the thread guide to rotate at the same speed as the pot. In this connection, means should be provided for starting and for stopping the delivery rolls when the spindles reach one-half speed.

No oil or grease is used inside the pot, and the bearings 24 are of the sealed-for-life type so that no oil soilage will occur. Lint 'or fly which may get into the pot I4 is brought to the top by the disc I2 when the machine traverses, and this foreign matter is thrown outwardly from the pot by centrifugal force when the upper edge of the projects slightly above the upper rim of the pot at the limit of the traverse. The disc [2 rides up onthe keys [6 to sweep the pot clean, and this also serves as a centering support to keep the pot concentric with the spindle. The wind vanes keep an'even tension on the thread; and as the diameter of the package increases the thread passes to a, different position on the thread guides set at an angle to prevent thread cutting.

"In Fig. 6 I have shown an arrangement for simultaneous twisting and cable twisting on a single machine. Spools l3 and I3 are filled with thread or fibers wound parallel, and the thread from these two spools passes upwardly through center thread'guides 34, 34", respectively, being pulled offfrom the'spools'so as to cause the thread strides to travel at a speed faster than the spindles and-twist the fibers thus thrown off into a-cord. These cords are carried up over delivery rolls 35, 35' and then pass through center thread guide 34 down to the third spindle where they are twisted into a single cable cord and wound onto thespool l3.

- Many modifications, adaptations and changes can be made in the embodiment shown without departing-from the scope of my invention as defined in the appended claims.
